Inspector;¬Module Inspectors
Some modules provide inspectors that BackSpace installs into its settings panel.  These inspectors allow you to tailor the behavior of individual modules.  Not all modules supply inspectors, however.

Priority;¬Priority
¬
Most applications run at a Mach priority of 10, but BackSpace is probably more frivolous than anything else you run, so you don't want it to take too much time away from other applications.  If you set a lower priority, other applications will get processor time at the expense of BackSpace rather than vice versa, so it shouldn't be too much of a pig.  I recommend a priority of 9 or lower.  If you run it at priority 0, it won't take much time away from other applications, but it will still run at full speed if no other application is requesting processor time.

BackSpace vs Zilla
BackSpace doesn't completely interfere with the use of the Zilla supercomputing application, because Zilla will be able to run anytime BackSpace is running its screensaver display (despite the fact that the screen doesn't appear to dim).  However, BackSpace can and will steal much valuable processing time away from Zilla.  If your machine is running Zilla and you want to run BackSpace, you should select one of the screen saver modules that spends most of its time sleeping rather than performing animation.  A good choice is the Black module, which performs no animation and will have negligible impact on Zilla, regardless of BackSpace's priority.
